Questions flooring contractors actually ask

Straight answers, no fluff. Then run your own numbers above.

How many boxes of LVP do I need?

Divide the room's square footage (plus 10% waste) by 20 — most LVP boxes cover about 20 sq ft. A 500 sq ft room with 10% waste needs 550 sq ft, or 28 boxes. The calculator above rounds up automatically.

How much waste should I add for LVP?

10% is standard for straight-lay rooms. Bump to 12–15% for diagonal patterns, herringbone, or rooms with lots of jogs and doorways — every angle eats a plank.

What does LVP cost per square foot installed?

$4–$10 per sq ft in 2026: $2–$5 for materials and $2–$5 for labor. Budget grades land near the bottom, premium 20-mil rigid-core near the top.

Do I need underlayment under LVP?

Only if your planks don't have a pad attached. Many rigid-core LVP products ship with attached underlayment — adding a second layer can void the warranty. If needed, budget about $0.50 per sq ft.
